在界面中添加了GirdView控件並增加數據源之后,在代碼中可以看見它的內容。
<div>
<asp:GridView ID="GridView1" runat="server" DataSourceID="EventDataSource" BackColor="White" BorderColor="White" BorderStyle="Ridge" BorderWidth="2px" CellPadding="3" CellSpacing="1" GridLines="None">
<FooterStyle BackColor="#C6C3C6" ForeColor="Black" />

<Columns>

說明:
DataSourceID:定義了與數據源控件的關聯。(DataSourceID="EventDataSource")
<Columns></Columns>:列出了用於顯示數據的所有綁定列
HeaderText:此列的標題
DataField:數據源中的字段名
<asp:SqlDataSource></asp:SqlDataSource>:定義婁數據源
SelectCommand:定義如何從數據庫中讀取數據
ConnectionString:定義如何連接數據庫(ConnectionString="<%$
ConnectionStrings:EventsConnectionString %>"),連接字符串我們保存在配置文件web.config中,所以用<%$ 與配置文件中動態生成的類之間建立關聯。
